asm-generic: rwsem: ensure sem->cnt is only accessed via atomic_long_*

2016-09-13T11:23:07+00:00

The asm-generic rwsem implementation directly acceses sem->cnt when performing a __down_read_trylock operation. Whilst this is probably safe on all architectures, we should stick to the atomic_long_* API and use atomic_long_read instead. Signed-off-by: Will Deacon
